การประยุกต์เทคโนโลยีสารสนเทศภูมิศาสตร์ เพื่อการวางแผนการใช้ที่ดิน สำหรับการเกษตรบางชนิดในอำเภอปากช่อง จังหวัดนครราชสีมา / สถาพร มนต์ประภัสสร = The application of GIS tecnique in some agricultural landuse planning of Amphoe Pak Chong, Nakhon Ratchasima province / Sathaporn Monprapussorn
To apply the Geographic Information System (GIS) to classify land suitability for three cash crops, namely, rice, corn, and cassava. Amphoe Pak Chong, Nakhon Ratchasima province is chosen as the study area. The characteristics of physical and environmental factors of land, such as, soil slope, soil drainage, soil depth, soil reaction, organic matter content, average temperature and average rainfall or water requirement, are analyzed and evaluated together with the existing soil grops. Considering the relationships between crop requirement and the factors of land, the suitability level has been designated into four classes so as to prepare maps depicting suitability of land for the cash crops in the area. Moreover, the user-interfaced application is developed through Arcview Macro Language (Avenue) of ArcviewGIS 3.0 for the user's convenience in viewing the maps. The findings of the present study could be used as the basis for planning of agricultural landuse to suit the physical and enviornmental characteristics of land. In addition, it will be useful for future studies when other factors have been taken into consideration, which have not yet been included in this study.
